Describe the shape of Earth's orbit. Where is the Sun located within the orbit? Explain.
Kepler's 1st law says that our Solar System's planets orbit in ellipses around the Sun where the closest distance to the Sun is called perihelion.
Suppose I tell you that there is a planet with a perihelion distance of 2 AU and a semi-major axis of 1.5 AU.
Does this make physical sense? Explain why or why not.
What changes when one is on the moon compared to Earth, weight or mass? Why? Explain.
